Jetpack Infinite Scroll with custom post type.

I’ve created custom post type with “CPT UI” plugin. I’ve added some custom posts via WordPress and loop through that posts in my static page – page-reviews.php. My loop:

<?php

$args = array(
	'post_type' => 'reviews_type'
);

$query = new WP_Query( $args );

if ( $query->have_posts() ) :

	/* Start the Loop */
	while ( $query->have_posts() ) : $query->the_post();

		/*
		 * Include the Post-Format-specific template for the content.
		 * If you want to override this in a child theme, then include a file
		 * called content-___.php (where ___ is the Post Format name) and that will be used instead.
		 */
		get_template_part( 'template-parts/content', 'reviews' );

	endwhile;

	the_posts_navigation();

else :

	get_template_part( 'template-parts/content', 'none' );

endif; ?>

<?php wp_reset_postdata(); ?>

I have also added “Jetpack Infinite Scroll” support to my theme:

function sandrasaenz_infinite_scroll_init() {
	add_theme_support( 'infinite-scroll', array(
		'container' 	 => 'main',
		'render'    	 => 'sandrasaenz_infinite_scroll_render',
	) );
}
add_action( 'after_setup_theme', 'sandrasaenz_infinite_scroll_init' );

function sandrasaenz_infinite_scroll_render() {
    get_template_part( 'render' );
}

The problem is – it doesn’t work for me. I don’t have id="infinite-handle" in my HTML. What’s wrong with my code?

Any help will be appreciated!
